Notably, Trump shared a photo depicting Bush picking his nose that appears to be an altered Reuters image of Bush with a finger on his lip.

The Republican front-runner also retweeted a supporter who claimed that Bush's mother was a Trump supporter.

"So cute!" Trump added.

Among the other Trump jabs was a shot at what Trump called the disastrous record of Bush's father, former President George H.W. Bush, and brother, former President George W. Bush. Trump also retweeted a supporter mocking Jeb Bush for attacking Trump while sagging in the polls of the GOP primary.

Earlier in the evening, Bush bashed Trump during a Fox News interview. Speaking on "The Kelly File," Bush brought up Trump's Democratic past and said Trump was "not a serious candidate and he would be, I think, a disaster as the party's nominee."
